be flush with the body of the shell. The

Be it known that I, ADOLPHUS J. LIARTIN, a citizen of the United States, and resident of Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Wooden Shells, of which the following isa specification.

This invention relates to a wooden shell for winding material thereon which is used by printers, bleachers, dyers paper, rubber and silk manufacturers; and it essentially provides reinforcing head members secured to the end portions of the shell body for preventing it from being split or marred.

One of the objects of the invention is to provide the head member with means for taking up practically all the strains exerted by the shaft or bar on which the shell is mounted.

Another object of the invention is to provide the head member with a rim flush with the periphery ofthe shell bodymade to absorb the shocks given to the body when it is taken from the bar and carelessly thrown down or placed endwise.

Another object of the invention is to provide the head member with radial arms or spiders having cutting edges embedded or feathered in the end of the body whereby the member is securely locked to the shell.

The invention resides more particularly in the novel combinations hereinafter described and claimed reference being made to the accompanying drawing in which Figure 1 represents a longitudinal vertical section of a shell embodying this invention.

Fig. 2 is an end view of the same.

Fig. 3 is a detail section of one of the arms taken along the line 8-3 of Fig. 2.

In the drawing the numeral 5 designates I a shell, the body of which is preferably made of wood with an angular bore 6 for mounting the shell on a square section shaft or bar as is well known. Each end of the shell is provided with a reinforcing metal head member having a web or hub 7 provided with a square hole 8 made to register with and correspond to the contour of the bore. At the upper end of the web is located an inwardly projecting annular flange 9 normally embedded in a groove formed in the end of the shell. A series of arms or spiders 10 radiate from the periphery of the flange to an annular rim 11 sunk. in a reduced end of the body so that the circumference will Specification of Letters Patent.

arms taper transversely as indicated in Fig. 3 'to form sharp'edges to cut intothe rim of the body, and the facesthereof' are depressed to coact with overlaid portions of the shell.

It will be observed, that the arms perform the functions of feathers or wings to prevent movement of the reinforcing head member relative to the body of theshell. When the head, member is driven into the end of the body the rim flange and the arms by frictional contact with the wood prevent displacement of the member. In other words the member is securely locked to the shell by merely hammering it into the end of a body provided with the reduced end and an annular groove for the inwardly projecting flange. The inner portions of the arms being sharp they will cut radial notches into the body between the flange and inner portion of the rim thereby wedging the member to the body. In order to absolutely prevent the head member from being displaced end- -wise,'the wood in the spaces between the arms can be hammered down forcing it over the depressed edges of the arms as indicated at 12 in Fig. 8 and the face of the rim.

A shell of the kind described is specially suitable for calico and other cloth printing machines where the roller comes in contact with water or steam and would be put out of action were it not for the metal heads driven into the end of the body. The load on the shell when mounted on a square shaft while in action is substantially taken up by the square hole in the central portion of the head member so that there is little danger of injury to the shell. The metal heads are preferably constructed of malleable iron giving them suflicient elasticity to withstandanyconcussion without breaking or cracking and in winding imitation leather or water proof fabric thereon so that it can be transported or shipped to any desirable place.

I claim:

.1. A shell comprising a body with a bore, a reinforcing head member having a hub member with a central hole registering with the bore, an annular flange projecting inwardly contiguous with the margin of the hub member, a series of arms extending from the flange embedded in the body, and a rim formed on the arms.

2. A shell comprising a body with a re The shell is used in cotton millsduc'ed end and an angular bore, a metal rea'reduced end and an an inforeing head member having a hub mem ber with an angular central hole registering with the bore, a flange projecting inwardly contiguous with the hub member, a series Of arms extending from the flange embedded in the body, anda rim formed on the armsfiting inwardly integral with the end of the hub member, a series ofradial cutting arms extendingfromthe' flange feathered in the 7 end of the body, the faces of the arms being depressed to coact with overlaid portions of the body, and a rim surrounding the arms made to embrace the reduced-end 'o f the 7 bed Signed at New York, in the county of New York and State ofNew York, this 27thday of September; A.
